摘　　要：文中以薄竖直板为研究对象,在有限水深情况下,保持板上端与静水面平齐,通过改变板浸深探讨相对浸深对消波性能的影响.采用CFD方法构建数值波浪水槽展开研究.与相关的试验结果和解析解比较,验证本文数值方法的正确性.数值模拟了7个相对波长、6个相对浸深的规则波与竖直板的相互作用;在竖直板迎浪侧和去浪侧设置波形测点,计算了透射系数、反射系数和能耗系数;分析了相对浸深和相对波长对消波性能的影响.并内插计算了50%、60%和70%等明显消浪效果时、7个相对波长下的竖直板相对浸深值列入表中,供防波堤浸深设计参考.Taking the thin vertical plate as the research object,under the condition of limited water depth,the upper end of the plate was kept flush with the still water surface,and the influence of relative immersion depth on wave-absorbing performance was discussed.CFD method was used to build a numerical wave flume,and the correctness of the numerical method in this paper was verified by comparing with the experimental results and analytical solutions of waveforms.The interaction between regular waves with 7 relative wavelengths and 6 relative depths and vertical plates was numerically simulated.Waveform measuring points were set on the wave-receiving side and wave-removing side of the vertical plate,the transmission coefficient,reflection coefficient and energy consumption coefficient are calculated,and the influence of relative immersion depth and relative wavelength on wave-absorbing performance was analyzed.The values of relative immersion depth of vertical slab at seven relative wavelengths were calculated by interpolation method,which could be used as a reference for the design of breakwater immersion depth.
